Objective: To endoscopic transoral approaches in the treatment of lesions in the occipital-cervical transverse ligament of the atlas provide anatomical support and explore Transoral endoscopic treatment atlas transverse ligament surgery feasibility and methods school. Method: ① Select the atlas vertebra of 50 sets of complete specimens, measuring the length of the anterior arch of the atlas and transverse ligament of atlas tubercle spacing. ② Select the 20 sets with soft tissue atlantoaxial complex specimens, measuring transverse ligament of atlas and its adjacent anatomical structures related data. ③ The 20 full head and neck were divided into two groups (traditional group with endoscopic group), respectively, according to the traditional and endoscopic approach Transoral transverse ligament of atlas explore the endoscope through the mouth pharynx approaches in the treatment of atlas transverse ligament surgery and treatment of the feasibility transverse ligament of atlas approach. Results: ① The length of the anterior arch of the atlas was 18.78 ± 2.4mm. ② transverse ligament of atlas tubercle spacing 17.82 ± 1.9mm. ③ transverse ligament of atlas arched convex to the rear, a length of 19.67 ± 2.4mm, its uneven thickness, Central thin and wide, thick and narrow ends. Transverse ligament of atlas about the width at the attachment points were 6.39 ± 1.2mm and 6.49 ± 1.3mm; around atlas transverse ligament attachment point of the thickness was 3.50 ± 0.8mm and 3.6 ± 0.8mm. At the midpoint of the width and thickness, respectively 10.34 ± 1.8mm and 1.96 ± 0.3mm. ④ midpoint film thickness 0.93 ± 0.2mm, the thickness of the left and right ends, respectively, of 2.48 ± 0.7mm and 2.52 ± 0.7mm. ⑤ midpoint transverse ligament of atlas and after about two attachment points at the edge of the dural sac minimum distance of 1.7 ± 0.2mm, 4.5 ± 0.8mm and 4.5 ± 0.8mm. ⑥ transverse ligament of atlas around the midpoint and at the trailing edge of the two attachment points with a minimum distance of the spinal cord were 4.0 ± 0.5mm, 8.1 ± 1.2mm and 8.0 ± 1.2mm. ⑦ transverse ligament of atlas two attachment points on both sides of the vertebral artery with a minimum distance of 11.8 ± 0.9mm and 11.9 ± 1.0mm. ⑧ atlas transverse ligament resection in dens after their deformation can occur, in which points can occur in the sagittal maximum displacement, size is 5.62 ± 1.3mm; cutting attachment points on its side after the midpoint in the sagittal on the distance traveled can be up to 11.70 ± 1.6mm. Conclusion: This study suggests that endoscopic treatment Transoral transverse ligament of atlas is technically feasible, not only to the traditional surgical approach of the operative field range, but also for the transverse ligament of atlas revealed more clearly , the operation more convenient and accurate. 2, endoscopic treatment of transverse ligament of atlas can be close to the side of the transverse ligament of atlas nodules, top-down, vertical cut off their attachment point method, generally only one side of the attachment point can be achieved by cutting decompression purpose; cutting operations transverse ligament of atlas depth can not exceed the \3, dens resection, transverse ligament of atlas rear there is a \On clinical judgment pathological state atlas transverse ligament need treatment of some help.
